IMPRovElvu-:N'r IN TEASELGRADING MACHINES.

The Schedule referred to in these LetterB-Patent and making part ef thename.

To all whom it may concern Be "it known that I, GEORGE A, BRROUGH, ofProvidence, in the State of Rhode Island, have'invented a new and usefulmachine, which Icall a Grad ing Machine for Grading Teasels, an articleused by wooleu manufacturers for raising the nap on cloths and otherarticles; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings making a part of thisspecification, in which like parts are represented by like letters inthe several figures, andin which- Figure 1 is top view;

Figure 2 is a sectional View; and Y Figure 3, a partial top View of astraight machine, which was rst made but not considered as good as fin.1.

DThe machine is made of iron or other materials, in a circular form,about four feet across the top, with about forty slots or spacesgraduated from threefquarters of an inch to one and a half inch wide andthree inches long, with a suitable number-of caps.

In the drawings, iig. 1-

a represents the seat for the operator.

b, graduated slots.

c, caps.

d, radial arms.

e, a rotary shaft.

t', supports.

j is a fixed exterior flange. The widthof the slots b is regulated bysections sof an annular ring concentric with the flange j, thesesections to 'be adjusted inward or outward by a parali lei movementthrough'slots k in the same and setscrews l, by which they are securedto the centertable or platform.

The machine is set in motion by power being applied in any suitablemanner to the shaft e, iig. 1, and the operator, at a, places theteasels in the cups with their stems in the `supports 'i to keep them ina perpendicular position as' they rotate over or through the graduatedslots, until they reach one suiiciently wide to allow of their passingthrough, as shown in fig. 2, f representing a teasel passing over, and gone passing through a slot, suitable receptacles A being providedunderneath to keep the sizesseparate.

What I claim as new, and desire to secure by Letters Patent of theUnited-States, is 1. In a teasel-grading machine, the graduated slots orspaces formed by the annular flange j, and the adjustable sections l,for the purpose set forth.

2. In combination with said slots, the radial rotary arms d, caps e, andsupports t, arranged as and for the purpose set forth.
